Altair Unit Licensing – A Quick Guide To clarify how Altair Units (AUs) work: Each Altair application or solver consumes a specific number of Altair Units (AUs). 1 AU equals 1000 license features. You can run any Altair product as long as enough license features are available and the required product license features are…
Abstract In this post, I explain the rule of Radioss default value of input cards. Rules No. 1: Blank → 0 When we create Radioss cards, we notice that there are many parameters which we do not input. Radioss treats those blanks as 0. No.2: 0 → Default value Radioss sets the parameters which we set to 0 or leave blank to a…
In the previous article we described the setup for the optimization of a buck converter with a Type 3 Controller. This workflow uses measurements from the output waveform to qualify the controller. But, what about the frequency domain characteristics? In this article we’ll show how to add Phase Margin and Crossover…
This session shows how to build surrogate AI models of PSIM power converters using Altair romAI. These AI reduced-order models (ROMs) can be used to run system simulations much faster, while still capturing system dynamics with high accuracy. Power converters in battery charging applications are often computationally…
